Check Atmosphere Pressure Using Arduino Mega 2560

In this article I will explain about checking the Atmosphere Pressure using Arduino Mega 2560.

Introduction
  • In this article I will explain about the checking the atmosphere pressure by using Arduino Mega 2560.
  • It can correctly give the range of pressure in the serial monitor.
Parts Of List
  • Arduino mega2560
  • MPX4115A
  • Dual power supply
  • LM741
  • Bread Board
  • potentiometer
MPx4115A
  • It can correctly give the air pressure in the atmosphere.
  • It can be a bamometer application.

LM741 Operation Amplifier
  • Very commpn type of OP-AMP, It provide overload production on the input and output
  • It can be easy to use.

Programming
  1. void setup()     
  2. {    
  3.    serial. begin(9600);    
  4. }    
  5. void loop()    
  6. {    
  7.    int sensorvalue = analogread(A0);    
  8.    float voltage = sensorvalue * (5.0 / 1023.0);    
  9.    serial.println(KPa)  
Explanation
  • In this article I explained about the checking the atmosphere temperature in the arduinomega2560
  • It can be connected in the digital meter and displayed in the serial monitor.
